BARREL-MAKING MACHINE.

SPECIFICATION forming part of Letters Patent No. 232,054, dated September 7, 1880.

Application filed November 20, 1879.

To all whom it may concern Be it known that we, DAVID MURRAY and THOMAS W. MoGnEeoR, of ltushford, in the county of Fillmore and State of Minnesota, have invented a new and Improved Barrel- Machine, of which the following is a specification.

The object of our invention is to provide in a single machine the several mechanisms and devices for trussing and working the ends of barrels, kegs, &c., preparatory to receiving the heads.

The invention consists in the construction and combination of parts, as hereinafter described and claimed.

In the accompanying drawings, Figure 1 is a plan of our improved barrel-machine. Fig. 2 is a vertical longitudinal section of the machine, taken on line 00 a; of Fig. 1. Fig. 3 is a crosssection taken on line y y of Figs. 1 and 2. Fig. 4: is a cross-section taken on line y y of Fig. 2. Fig. 5 is a sectional front elevation of one of the face-plates and part of the trussing mechanism. Fig. 6 is a vertical longitudinal section of the face-plate and trussing mechanism, taken on line 2 z of Fig. 5; and Fig. 7 is a detail of the devices for operating the rnovable knives of the face-plates.

Similar letters of reference indicate corresponding parts.

Referring to the drawings, A is the frame of the machine. B is the main driving-shaft, carrying the pulley a on one end, which isfto be belted to the driving-pulley of the power which operates the machine.

Inside of the frame, on shaft B, are pulleys b b, held in connection with the shaft by feathers 11 which turn with said shaft, but are adapted to move back and forth to and from each other. Beyond pulley b a pinion, c, is placed loosely on shaft 13. On the back of pinion c is an annular conoidal flange, 0. At the end of shaft 13 another loose pinion, d, is placed on said shaft, which is likewise pro vided with an annular conoidal flange, d, facing flange 0.

Between pinions 0 cl are placed on shaft B double-conical friction-clutch plugs C G, joined by a neck, 0 which slide back and forth on feather 6, so that they can be made to engage flanges c or d at will, for the purpose of communicatin g the motion of shaft B to pinions 0 d, or to occupy a midway position between said flanges and throw the pinions out of gear and allow shaft B to rotate independently of said pinions.

In the upper part of the frame A are fixed two shafts, D D, parallel to each other. Shafts D D are each provided with right and left screw-threads c c. On screw-threads e are burrs f, and on threads 6 are similar burrs f. Between burrs f is held a ring, E, and between burrs f is held a second ring, E. Rings E E form the ends of the trussing mechanism. Arms 9 g project from rings E E on each side within shafts D D, and to the arms 1 g are fastened the ends of the semi-elliptical dovetailed grooved guides g 9 In guides g respectively. are held by a dovetailed joint the segments h h, which are coupled together in pairs by pins h.

The segments are rigidly connected by rods h attached to pins W, with the bar h, which lies on top of shaft B, and is held 011 top of said shaft by a U-shaped guide, It", extending down on each side of said shaft.

The endsi i of bar h are turned up at right angles and provided with teeth i, which are engaged by the ratchet-wheels i on shafts i Shafts i carry grooved pulleys j. Around said pulleys are run cords j. One end of each of said cords is attached to a spring, i while the opposite ends are attached to a foot-treadle, E By pressing on treadle E the cords j are caused to rotate pulleys j and shafts i and the ratchet-wheels i engaging teeth 6, raise the bar 71., and the rods 71. throw the segments h h up in the direction of arrows 1, Fig. 5. On releasing the treadle E the springs j, acting on the several parts mentioned in a reverse direction, draw the segments h h down to the position segments h are shown to occupy in Fig. 5.

The function of the segments h h is to truss or force the hoops onto the barrel. The segments are made detachable from the guides to allow substitution of others of different curvature-that is to say, of a curvature corresponding to the barrel being trussed, &c.

The barrels are centered by and supported upon a rest, j Figs. 2 and 6, which consists of a curved bar having a suitable fixed support.

Within the rings E E, respectively, are se cured beveled rings E E, which serve as means for forcing the end hoops on the barrel. The rings E E are held by clamp-screws, and thus adapted for being conveniently detached, when required, for the purpose of substituting other rings ofless diameter for use in trussing smaller barrels.

Back of rings E E, respectively, are crossheads It It, supported and sliding freely on shafts D D. Gross-heads k are connected together by rods the ends whereof are hooked to burrs f, and cross-heads 7c are connected by similar rods is, hooked to burl-sf.

In cross-heads 7c is journaled a shaft, F, and in cross-heads 7c is journaled a similar shaft, F. Shaft F carries a pulley, l, which is belted to pulley b and a circular face-plate, F close to ring E.' Shaft F carries a pulley, l, which is belted to pulley b and a face-plate, F close up to ring E. In face-plates F and F are radial slats Z l l, in which are confined, by dovetailed joints, plates at m m respectively, and to said plates are fixed heads at m 012 In head m is fixed the chamfering-knife n. In at is the evening-knife n, and in m is the crozing-knife n All of these knives are attached to the said heads with their points projecting out between the heads and the beveled rings E E At right angles to the edge of the chamfering-knife at an edging-knife, n is passed through an opening, at, in the faceplates F F so that its cutting-edge forms a right-angular continuation of the edge of the chamfering-knife. The purpose of knife n is to trim off the ends of the staves, and thus level the ends of the barrels, &c.

On the backs of each of the plates m m with which the eveningknife n and crozingknife n are connected, is arack, 0, projecting into an opening,0',extending entirely through the face-plates. Racks 0 mesh with spurwheels 0 pivoted in cars extending front the face-plate on each side of the openings 0. Spur-wheels 0 also mesh with racks 0 on sleeves G G, Said sleeves are placed on shafts F F and extend over the hubs or sleeves of the face-plates, and they have a free sliding movement, which is limited in the direction of the face-plates by the ends of the hubs,and in the opposite direction by collars p, placed on the shafts. The sleeves G G, being connected with the shafts F F by a feather, are rotated with said shafts.

The purpose of the sleeves G G, racks o 0 and spur-wheel 0 is to throw the eveningknife n and crozing-knife a up in the direction of the arrows 2, and thus bring them in contact With the inside of the ends of the barrels after the chamfering and leveling is completed, and also to move them back while the chamfering and leveling is being done. The movements that adjust the said knives are produced by the sleeves G G in thefollowing manner: When the sleeves G G are moved in the direction of arrows 3 the racks 0 turn the spur-wheels 0 in the direction of arrow 4, and Said spur-wheels 0 throw the racks o, and

with them plat-es m m and knives n W, in the direction of arrows 2. When the sleeves G G are moved backin the opposite direction from arrow 3 the movements of the several recited parts are reversed and the plates m m and knives n n are thrown in an opposite direc tion from that indicated by arrows 2.' The backward movements of sleeves G G are produced automatically by springs 19, wrapped around shafts F F, between the parts of the sleeves on the said shafts and the ends of the hubs of the face-plates, in the manner clearly shown in Figs. 2 and 6. The forward movements of sleeves G G are produced by levers H H, having forked ends 12 which are loosely connected with the respective sleeves. The power ends of said levers H H are held respectively in the forked ends of rods 12 (see Fig. 7,) which have their opposite ends pivoted to a plate, I, on opposite sides of the center of said plate, so that when said plate is turned on its axis the rods 113 will move in opposite directions. The plate I is provided with an arm, g, which is pivoted to one end of a rod, q, the opposite end whereof is pivoted to the weight end of a lever, I. \Vhen lever I is thrown up in the direction of arrow 5, through rod q, plate I, and rods p levers H H are moved in the direction of arrows 6, and these movements of said levers throw the sleeves G G in the direction of arrows 3, with the resulting effect of moving the evening and crozing knives out in the direction of arrows 2. As soon as the lever l is relieved from pressure the springs 1) reverse the movements of lever H H and all connected parts.

As before stated, the shaft 13 moves independently of spur-wheels c d, and this independent movement is communicated through pulleys b b by belts to the pulleys l l, shafts F F, and face-plates F F so that said faceplates have an independent rotary movement. At the same time said faceplates, together with the cross-heads k k, rings E E and pulleys Z Z, have a reciprocating movement which is communicated to them in the following manner: Pinion 0 gears with an idle-wheel, J, which, in turn, gears with spur-wheels J J, fixed respectively to shafts D D. When shaft B rotates to the right, if the pinion c is engaged by the clutch, it communicates motion through the idle-wheel J to spur-wheels J J, which are thereby turned in the direction of arrows 7, and the same motion is given to shafts D D. This causes the right screwthreads 0 to throw the burrs f and attached parts in the direction of arrow 8, and the left screw-threads c to throw burrs f and attached parts in the direction of arrow 9. To reverse this movement without changing the motion of the main shaft B a spur-wheel, K, is fixed to shaft D, which meshes with the pinion d, so that by throwing pinion cl into connection with shaft B through the clutch the spur-wheel K, shaft D, and (through the spur-wheel J,

idle-wheel J, and spur-wheel J) shaft D are rotated in the direction of arrow 10, whereby and within the collar 1'.

the movements of burrs ff are reversed, and the rings E E, face-plates F F and con: nected parts are moved from each other in a direction opposite to that indicated by arrows 8 9, Fig. 2.

The reverse movements are brought about by the clutch, composed of annular flanges c d and conical plugs O O. The conical plugs are moved by a lever, L, provided with a yoke, T, which incloses and is pivoted to a collar, 1", held in an annular groove in the neck 0 that connects the two plugs (J O. The said plugs, being feathered to sh aft B, turn with said shaft By throwing plug 0 into connection with flange c the pinion c is caused to rotate with said plug, and by throwing plug 0 into connection with flange d pinion d is caused to rotate, while pinion 0 comes to a stop. By placing the plugs G C out of connection with both flanges c (1 both pinions c 61 remain stationary.

For convenience in operating the machine the power end of lever L is connected by a rod, 8, with a brake-lever, L, the power end whereof is held under a guard, 8, provided with a middle notclns for holding the brakelever L, and through it to hold the plugs G C out of connection with the flanges c d. Lever L is also connected by a rod, t, with a stoplever L the power end it whereof extends up in the line of travel of the finger t, attached to the outside cross-head, 70', so that when said cross head is being moved backward on shafts I) D the said backward movement is stopped by the finger t striking the lever L and moving said lever suiiiciently to disconnect the clutch and stop the movement of pinions c (I.

As the pulleys l I receive their motion from pulleys b b, it is necessary that the latter shall follow the movements ofpulleys l I when carried backward and forward by the movement of the burrs f f on shafts D D. For this purpose rods u to extend down from crossheads k is, respectively, and yokes n n on said rods are placed in grooves ww in the hubs of wheels I) b. As wheels I) b are feathered to shaft B and slide freely back and forth 011 said shaft, the rods to a carry the. pulleys b I) back and forth with the cross-heads 70 k, and thus keep them in line with pulleys Z 1.

Having thus described our invention, we claim as new and desire to secure by Letters Patent 1. The combination of the curved rests with the rings placed vertically for receiving the ends of the barrel-staves, the curved segments h h, and movable slotted guides g 9 said rests being supported and arranged horizontally contiguous to the lower portion of the rings, as shown and described.

2. In combination with the evening-knives n and crozing-knives W, the sleeves G G, sliding on main shaft, and spur -wheels and ratchets interposed between said sleeves and the crozing and evening knives, in the manner and for the purpose substantially as described.

3. The combination, with the evening-knife n and crozing-knife 42?, attached respectively to plates m m racks 0, and spur-wheels 0 with sleeves G G, having racks 0 the springs 19, rods p plate I, connecting'rod q, and lever 1, substantially as and for the purpose specified.

4. In combination with segments h h, guided in ways g 9 the rods k bar if, provided with a U shaped guide, if, and ratchet-teeth 13', the pinions i grooved wheels j, cords j, springs j and treadle E as operative mechanism to work the segments, substantially as described.
